摘要
针对某110kV变电站全站失压造成大面积停电的问题,从断路器保护动作和主变压器保护动作两方面进行分析,认为某化肥厂大型电机反馈电源在主变压器110kV侧产生过电压是造成本次故障的原因,提出相应的处理措施及建议,并说明处理效果。
;For the fault of large area blackout caused by a 110 kV transformer substation substation voltage loss, this paper analyzes from two aspects of circuit breaker protection and transformer protection action,considers that the large motor feedback power of a fertilizer plant caused over-voltage in the 110 kV side of transformer is the causes of the failure,and puts forward the corresponding measures and suggestions, explains the treatment effect.
